"My Girl" is the Temptations' signature tune. Written and produced by two of their Motown labelmates, Smokey Robinson and Ronald White of Smokey Robinson and the Miracles, it was the group's first number one pop hit. Robinson and White wrote "My Girl" when the Miracles were performing at New York's Apollo Theater. Returning to Detroit, Robinson began recording at Motown's in-house studio with the label's session band, the Funk Brothers. The track begins with James Jamerson's bass line, which mirrors a gentle heartbeat. Along with Robert White's sinewy guitar lines, it's one of pop music's most recognizable melody riffs. "My Girl" was a magnificent showcase for David Ruffin, who'd just been given the lead vocal spot previously occupied by Eddie Kendricks and Paul Williams. Paul Riser wrote his superb arrangements after listening to Robinson singing the song while playing the piano. His skill made fine use of members of the Detroit Symphony Orchestra. "My Girl" went to number one R&B for six weeks and number one pop in early 1965. Portions of the classic were used for the Temptations' 1998 hit single "Stay" from their platinum CD Phoenix Rising.
